How to Choose a Down Sleeping Bag

Down sleeping bags use duck or goose down, the fluffy feathers birds use for insulation. As of yet, no made-made fiber has matched the warmth-to-weight ratio of down. Compressible and lightweight, down is the choice for traveling small and light. Look for the EN, or European Norm, rating. This industry-wide standard gives you an idea of the lowest temperature at which a bag will keep you warm.

Down
Down bags have a fill rating that indicates the amount of volume one ounce of down occupies. The higher the fill-rating, the loftier the down. It provides more warmth with less weight.

Shape
Mummy-shaped bags taper towards your feet to reduce volume and hold warmth closer to your body. These bags can feel restrictive to some. A semi-rectangular bag can offer more room to move.

Moisture Management
Down insulates less when wet. Some bags feature hydrophobic treatments on the outer fabric or on the down itself (like DriDown) to keep the down insulation dry.
